Wave Life Sciences Announces Oral Presentation of Preclinical Data Supporting WVE-007’s Mechanism (INHBE) to Reduce Fat, Preserve Muscle, and Induce Healthy Weight Loss at ADA's Annual Scientific Sessions

Core Insights - Wave Life Sciences Ltd. presented preclinical data supporting WVE-007, a GalNAc-siRNA targeting INHBE mRNA, as a potential novel treatment for obesity, demonstrating significant weight loss and muscle preservation [1][2][3] - The data indicate that WVE-007 can reduce inflammation in adipose tissue and lower pro-inflammatory M1 macrophages, suggesting a mechanism for reducing risks associated with type 2 diabetes (T2D) and coronary artery disease (CAD) [1][2] Group 1: Preclinical Data and Mechanism - A single dose of INHBE siRNA resulted in a robust reduction of INHBE mRNA and Activin E protein, leading to weight loss primarily through fat mass reduction [3] - The treatment showed a decrease in visceral adipose mass and preserved muscle mass, indicating a restoration of healthy adipose tissue [3] - INHBE siRNA significantly reduced the infiltration of activated macrophages in visceral adipose tissue, shifting the inflammatory state towards a less pro-inflammatory profile [3] Group 2: Clinical Implications and Future Trials - WVE-007 is being evaluated in the ongoing INLIGHT clinical trial for adults with overweight or obesity, with initial clinical data expected in the second half of the year [2] - The therapeutic profile of WVE-007 is differentiated from existing treatments like GLP-1s, as it operates through a unique mechanism that does not impact appetite directly [2] - The potential for infrequent dosing of WVE-007, possibly once or twice a year, could transform the obesity treatment landscape [2] Group 3: Genetic Evidence and Therapeutic Target - Human genetics strongly supports INHBE as a therapeutic target, with individuals carrying a protective loss-of-function variant showing a healthier cardiometabolic profile [2] - These carriers exhibit lower abdominal fat, triglycerides, and reduced risk of T2D and cardiovascular disease, reinforcing the relevance of targeting INHBE [2] Group 4: Company Overview - Wave Life Sciences is focused on RNA medicines, utilizing its PRISM platform to develop treatments for various disorders, including obesity [5] - The company aims to deliver scientific breakthroughs through its diverse pipeline, which includes clinical programs targeting multiple diseases [5]
